Practical Notes

Ensure the specified stainless steel grade (Grade X04Cr18Ni9 of IS 6603) is used, as this is crucial for corrosion resistance.

The strength of the entire locking system heavily depends on the quality of fasteners used to fix the bolt and staple to the door and frame.

For security applications, verify the staple fully shrouds the padlock shackle to prevent easy cutting.
